Anonymised, illustrative composite. A paving contractor kept bidding every municipal resurfacing tender that came out — until it looked honestly at what qualifying for those specific jobs was costing it.
At a glance
A family-run paving contractor in Ontario had built a habit of bidding on nearly every small municipal resurfacing tender that came out in its region — roughly nine a year, most in the $60,000 to $110,000 range, alongside a smaller number of larger private commercial jobs.
Municipal resurfacing tenders in the firm’s region routinely required Certificate of Recognition (COR) status to prequalify. Maintaining COR meant an annual audit cycle, correcting whatever the audit flagged, and paying for the review before it happened. For a firm chasing nine tenders worth roughly $87,000 on average, that annual overhead was being amortized across a shrinking set of low-margin municipal contracts — not the larger private work the firm was also capable of winning.
IHSA does not publish a COR audit fee on its program page — it directs firms to contact the program office directly — so no specific dollar figure is quotable here. What is quotable is the audit standard itself: a firm has to clear a minimum of 65% in each element and an overall score of 80% under the common national audit instrument, and IHSA requires pre-payment before the review proceeds. That is real, recurring administrative load, whatever its exact cost, set against contracts averaging under $90,000.
The firm ran the comparison it had never actually written down: the audit and corrective-action cycle it maintained specifically to keep bidding sub-$100,000 municipal jobs was proportionally the same cycle it needed to bid $300,000-plus private commercial contracts, which did not carry the same COR prequalification requirement in the firm’s own client base. Chasing the small municipal tenders was not free; it was the same fixed cost, spread over less revenue per contract.
It kept its COR certification — large private clients still valued it — but stopped submitting on the smallest municipal resurfacing tenders specifically, on the basis that the certification’s ongoing cost was being justified by contracts too small to carry it efficiently.
The firm now bids four to five larger private commercial paving contracts a year in place of the nine small municipal ones it used to chase, each contract larger than the municipal average it replaced. COR status stayed current either way, since the private clients still expected it — the change was in which tenders that certification was being pointed at.

Had the firm kept chasing all nine municipal tenders alongside the larger private work it was also capable of winning, its two estimators would have priced roughly 13 to 14 opportunities a year instead of the smaller, larger-average set it settled on — spreading the same fixed COR audit-and-correction cycle across more contracts, not fewer, at the lowest average value in its pipeline. Nine municipal jobs at roughly $87,000 average total about $783,000 a year; 4–5 private jobs above $300,000 average total well over $1,350,000, on roughly half as many submissions — the opposite of amortizing a fixed cost over smaller work.
Compare your average contract value inside a certification-gated segment against your average contract value everywhere else you bid. If a fixed, recurring audit or documentation cycle costs roughly the same regardless of contract size, and one segment's average value is a fraction of another's, that segment is carrying a disproportionate share of the certification's cost — whether or not IHSA publishes a number to prove it.
Dropping COR entirely was never actually on the table. The firm's larger private commercial clients treat COR status the same way municipalities do — as a prequalification proxy for safety maturity — so the certification's value did not disappear when the firm stopped chasing the smallest municipal tenders; it simply stopped being justified by them specifically. A certification kept for reasons unrelated to the segment being dropped is what economists would call a sunk cost with an independent reason to exist — it should never, on its own, be read as a reason to keep chasing every tender that happens to require it. The firm's decision was narrower and more specific than "is COR worth it": it was "which of the contracts requiring COR are actually worth the audit cycle," a question the municipal tenders answered clearly once someone ran the comparison.
